Compare performance near the router, ideally over Ethernet, with performance in the rooms where calls, study or streaming are affected. If the connection is poor throughout the home, check for a service problem and what broadband is available at your address; if it works near the router but not in particular rooms, choose equipment around those rooms, available cabling and where additional units can be placed.
Calls or streaming work near the router but falter in a bedroom, study area or another floor. The practical question is where and how to extend the in-home signal; Ofcom notes that building materials and router placement can affect Wi-Fi around the home.
Work, study, calls and entertainment happen at the same time, so it helps to determine whether the broadband connection or the home Wi-Fi is limiting use. Ofcom advises checking who is using the connection and what they are doing when investigating problems.
If a cable can reach a room that needs Wi-Fi, a wired access point or wired-backhaul mesh may be worth weighing against a wireless extender. Check the selected equipment’s access-point, connection and power requirements.
Ofcom advises comparing the broadband service with the Wi-Fi connection inside the home: a new wireless setup cannot make the incoming service faster. Use the checks below to identify which problem you need to solve before choosing equipment or changing service.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage across rooms and floors | Compare the same activity near the router and in each weak room; note walls, floors, possible unit positions and whether Ethernet can link units. | If calls work by the router but falter in bedrooms or on another floor, I want coverage where the household actually uses Wi-Fi. Around 31% of consumers put room-to-room coverage first. |
| Several people online at once | Note whether problems occur only at busy times, affect all rooms or one device, and persist when a suitable device connects over Ethernet. | When work calls, study and streaming overlap, I need to know whether the whole household is affected or only one wireless area. Around 23% of consumers prioritise capacity for simultaneous use. |
| The incoming broadband service | Compare wired results with the service you expect, investigate faults with your provider, and check address availability and offered speeds before switching. Ofcom cautions that checker predictions may differ from actual property availability and speeds. | If the connection is poor even near the router, I want to check the service before buying more Wi-Fi equipment. Around 23% of consumers put the incoming broadband connection first. |
| A cable-reachable room | Confirm the Ethernet route, access-point or uplink mode, available ports and the exact power method for the equipment. | When Ethernet can reach the room where Wi-Fi is needed, I want to avoid relying on a wireless relay for that link. Around 15% of consumers prioritise a wired-fed room. |
| One localised weak area | Test an intermediate socket that still receives a usable signal and confirm compatibility between the exact router and extender versions. | If one area is weak and the rest of the home works, I want to see whether a small extension can reach it from a usable position. Around 8% of consumers prioritise a localised extension. |
Wi-Fi equipment cannot deliver more than the broadband service brings into the home. If the service is the limiting factor, new coverage equipment may leave the underlying problem unchanged.
Before spending on equipment, compare a near-router or wired result with performance in affected rooms and investigate service faults or address-level options.
Test in the same conditions near the router and in the weak rooms. If performance is poor throughout the home, check the provider and available services before choosing Wi-Fi equipment.
An extender needs a usable signal from the router to relay. A socket in the very area where Wi-Fi has already failed may not provide that link.
A device placed without a usable upstream signal can add equipment without fixing the room’s connection.
Try an intermediate position that still receives a usable signal. If that is impractical but Ethernet reaches the room, compare an access point or a mesh system with wired backhaul.
Ports, power arrangements and mesh compatibility can vary between products and versions. A feature listed for one unit should not be assumed for another.
Choosing the wrong connection or power arrangement may mean changing the setup or buying different equipment.
Check the complete model, hardware version, included units and manufacturer documentation before choosing. Confirm the exact compatibility needed for your existing router.
Its Archer routers, Deco mesh systems and RE-series extenders illustrate different approaches to a single-router setup, multi-room Wi-Fi and a local weak area.
The eero 6+ line includes a mesh router and a wireless-only extender, so the included unit matters when planning a connection by cable.
The UK RT-AX58U is an example of a Wi-Fi 6 router that ASUS says can be expanded with compatible AiMesh routers.
Orbi 770 mesh packs are an example of a multi-unit system for households considering multi-gig ports and wired backhaul.
The U6+ illustrates a wired access-point approach for a household able to install and manage a separately powered unit; it is marketed principally for small and medium-sized businesses.
These Joybuy options cover multi-unit mesh Wi-Fi and replacement routers for households considering room-to-room coverage or a change of router. Check the exact connection needs and compatible equipment before choosing.

A three-unit mesh setup may suit a household weighing coverage across several rooms; placement still needs to provide a usable link between units.
The Joybuy listing identifies WiFi 7, dual-band operation, BE3600 and 2.5Gbps Ethernet. It also says a high-speed internet connection and an existing modem or gateway are required.
No image available
A three-pack may be relevant when several rooms need Wi-Fi; consider where each unit can be placed and whether the setup suits your home.
The Joybuy listing identifies the BE22 as a BE3600 Wi-Fi 7 mesh system in a three-pack. If wired links between units matter, check the connection options for the exact pack before choosing.

This router may suit a household considering a router change and possible later coverage expansion; check that the router meets your connection requirements.
The Joybuy listing identifies a BE9500 Wi-Fi 7 mesh router. For expansion, check which compatible units are required for the intended setup.

A single-router option may suit a home where the incoming service works and the rooms needing Wi-Fi are within reach of one well-positioned router.
The Joybuy listing identifies an AX5400 tri-band Wi-Fi 6E router. Wi-Fi 6E features require compatible client devices; the listing also conditions OneMesh on a compatible TP-Link extender.

A three-pack may be relevant when several rooms need Wi-Fi; plan unit positions around the areas where household devices are used.
The Joybuy listing identifies a BE9300 tri-band Wi-Fi 7 whole-home mesh system in a three-pack. Check the included equipment and connection options against your layout.
Compare performance where the problem occurs with performance near the router and, if possible, over Ethernet. If the connection remains poor near the router or over a wired connection, check for a fault and discuss the service with your provider; if it works near the router but not in another room, investigate in-home Wi-Fi.
Choose a position that still receives a usable connection from the router and can reach the problem area. TP-Link’s RE705X setup guidance advises moving the extender closer if its signal indicator shows an inadequate link; building materials and router position can also affect the result.
Yes, if Ethernet reaches the intended position and the selected device supports access-point operation. The TP-Link RE705X supports access-point mode; a PoE-powered model such as the Ubiquiti U6+ also needs a compatible power source.
Ask your provider whether it can supply a newer router and whether it supports third-party equipment. Before switching, check contract charges and installation or equipment steps with the providers; Ofcom says your current provider sends information about applicable charges during One Touch Switch.
No. The Ofcom checker shows predicted services and speeds, and Ofcom warns that actual availability and speeds at a property can differ. Confirm the address and the package you can order directly with a provider.
